Background: Farm profitability depends on raising healthy calves, which rests on successful feeding and management programs. Objective: To determine the effects of weaning weight on growth performance, feed efficiency, behavioral traits, as well as feeding cost of Holstein-Friesian and Brown Swiss calves. Methods: Sixty-seven newborn dairy calves were allocated into four weaning-weight groups [60 kg (n=18), 65 kg (n=19), 70 kg (n=18) and 75 kg (n=12)]. Body weights (BW) and measurements were recorded at birth, weaning, and four months of age. An instantaneous sampling method was used to collect behavioral data. Results: Daily weight gain of Brown Swiss calves was higher than Holsteins between weaning and four months of age (p |
